So if you're on macOS Sierra (10.12) or earlier and you ran hdiutil and see references to Apple_APFS or error 112, the issue is likely legitimate incompatibility, and this disk image won't open on this Mac without an update to the operating system.
MacOS Sierra (10.12) and earlier is not able to mount the new Apple File System (APFS). This will fill in the location of the dmg file into your Terminal window. Add a space at the end, but don't press enter yet.ĭrag the dmg file from your Finder window onto the Terminal window and let go.
Type hdiutil attach -verbose into the terminal. Open Terminal: In Spotlight, the search magnifying glass at the upper right corner of your screen, search for Terminal, and press enter to open the Terminal app. We will at least get some sort of useful error message to go on if it still fails: Try mounting the DMG on the command line in Terminal. Apparently there is an issue sometimes after opening too many dmg files, that is fixed with a reboot. Reboot your Mac if you haven't already tried that. (There's an example of that in my screenshot below.)
Or if you don't need to be logged in to the site to download the file and you want to be fancy, you can try curl -O url in Terminal to download the file. You can try downloading the file in a different browser as well. If possible, try downloading the dmg again, turning off any download assistant plug-ins you may have. In most cases, the downloaded dmg file is actually corrupt or had an error downloading. If you see the "no mountable file systems error" while opening a dmg, here's what you should try: The error was as the screenshot above shows trying to open a dmg (disk image), macOS showed the error "no mountable file systems". I didn't find a lot of good search results addressing the issue, so I decided to write up a post about it myself. There’s even a built-in title maker and multitrack picture-in-picture users can switch between sources on the fly by pressing the number keys that correspond to each.I ran into an interesting macOS error while working with a customer.
MultiCam is easy to set up and use, with familiar Source and Preview windows at the top, multicam and PiP in the center, and timeline across the bottom. New in Toast 17, capture and edit video from you Mac, webcams, and other sources while recording. The standalone app allows users to record from up to four sources at once, including the FaceTime HD Camera, your Mac display, and other attached audio or video hardware, which are automatically enabled by default. The newly christened MultiCam Capture and Editing makes it a snap to create training videos and other presentations for posting on YouTube or elsewhere.
Others like photo-centric Painter Essentials 6, Corel AfterShot 3, and FotoMagico 5 help justify the cost of the bundle, but most users will already own similar (or superior) tools for such tasks.Īfter adding MultiCam Capture to the Toast 16 lineup, Roxio has gone a step further in this version, beefing the up software with editing capabilities as well in both the Titanium and Pro versions. Some additions make sense, like MyDVD (introduced in Toast 14), which supports slightly more advanced disc authoring options like custom menus and chapter stops. Over the last several releases, Roxio hedged its optical media investment by bundling Toast with a suite of like-minded creative software. It’s worth noting that Blu-ray support is no longer activated when installing the Pro version the option is now tucked away in the Help menu instead.Ī darker, more responsive user interface, and no more usability bugs, Toast 17 Pro makes the venerable disc authoring software ready for macOS Mojave and beyond. That’s not necessarily a bad thing, although I’d love to see at least the Pro version adopt the same kind of comprehensive Blu-ray and DVD authoring tools found in Adobe Encore, which was discontinued in 2012. I’m not sure if Roxio’s engineers got tired of me bringing it up in reviews or the bug was finally squashed in the move to 64-bit, but there’s no longer any lag or spinning beach ball when clicking between tabs.Īside from the aforementioned fresh coat of paint, the core Toast application is otherwise largely the same as it’s been for years. Toast 17 addresses a long-standing annoyance I’ve had across multiple versions of the application when switching to the Video tab from other modes (Data, Audio, Copy, or Convert). The streamlined Toast 17 installer now downloads as a smaller file, then grabs remaining content from the internet as installation takes place.
